Backwards Suitable video games can’t join

Making an attempt to play L4D2 on my Xbox sequence X, however each time it tries to check in I get this display screen with this error code. To date I’ve tried: -Clearing 360 cache -Clearing native saved video games -Energy biking my console -Altering my IP, DNS, and MAC settings -Energy biking my router -Manually coming into IP handle -Uninstalling and reinstalling recreation

The one factor that has labored up to now is connecting to a hotspot, however I can’t play the precise recreation on the hotspot with out lagging out. Is there any answer we haven’t already tried?
